What is DEX.AG?

DEX.AG is a DEX aggregator. In other words, DEX.AG gets you the best price for your trade across multiple decentralized exchanges (DEXes), even splitting up your trade via our X Blaster if it improves the price.

What is the X Blaster?

When you make a large enough trade on a single DEX, the size of your order affects the price. DEX.AG’s X Blaster feature splits up your trade into smaller ones and spreads them across multiple DEXes to make sure you’re getting the best possible price for your trade.

How does DEX.AG work?

Enter the token and amount you’d like to swap and then hit the ‘Find trades’ button. DEX.AG scans every supported decentralized exchange and provides you with a list of available trades sorted by price. Prices update in real-time so there's no need to refresh the page.

Trade directly from DEX.AG using our ‘Buy Now’ button. All you need is an internet connection and an Ethereum wallet loaded with some ETH. Don’t have a wallet yet? We recommend Metamask.

When you click the ‘Buy Now’ button, DEX.AG takes the details of the trade that you’ve entered and prepares a transaction for the DEX you’ve selected. Next, follow the prompts of your wallet provider to submit your transaction. Your trade is complete as soon as it's confirmed on the Ethereum blockchain.

What fees are associated with trading on DEX.AG?

How do limit orders work on DEX.AG Pro?

When you place a limit order, you set a target price and amount you're willing to buy or sell. Then, you sign a transaction with your maker trade order. This trade order is placed on our 0x order books where it can be filled by 0x trades on DEX.AG. Placing a limit order costs 0 gas fees (unless you decide to cancel it) because the trader who fills your limit order pays the gas to submit the TX.

What is gas and how do I determine what gas price to use?

Sending transactions on the Ethereum network costs network fees in ETH called gas. We recommend you check ETH Gas Station for the current recommended gas prices.

What is WETH? Do I need to use WETH for DEXes like 0x v3?

Wrapped Ether (WETH) is an ERC-20 token representing ETH. Ether (ETH), the native currency of the Ethereum network, predates the forming of the ERC-20 token standard. And so, it's common for smart contracts like DEXes to require ETH to be "wrapped" in order for it to function like any other ERC-20 token. WETH can always be 'unwrapped' 1:1 for ETH.

With the exception of limit orders, when you make a trade on a DEX that uses WETH, DEX.AG automatically detects whether your ETH needs to be wrapped into WETH before sending it to make your trade. This all happens behind the scenes for your convenience. You can wrap and unwrap WETH on DEX.AG in the Balances page under our Pro Trading interface.

How do I wrap and unwrap WETH<>ETH on DEX.AG?

Some features on DEX.AG's Pro Trading interface require the use of WETH.
To wrap and unwrap WETH:
Navigate to DEX.AG Pro Trading. Connect your wallet and proceed to the 'Balances' tab. Under the 'Actions' column next to ETH, click the 'Wrap'. Then, enter the amount of ETH you'd like to wrap and press the 'Go!' button. Follow your wallet's prompts to confirm the transaction. Once your transaction is confirmed, the WETH will be shown under your balances page. Unwrapping WETH back into ETH is as simple as clicking the 'Unwrap' next to WETH under 'Balances', entering the amount you want to unwrap, and submitting your transaction as before.

What's the address of DEX.AG's proxy smart contract?

What’s going on when my Bancor trade fails?

Increasing the default gas price while sending a trade to Bancor will cause the transaction to fail. This happens because when DEX.AG executes a trade through Bancor, Bancor sets the maximum gas price that they are willing to accept. You can lower the gas price of your trade, but anything above the default gas price will result in a failed transaction.

What’s going on when my 0x v3 trade fails?

When you send a trade to 0x v3, you’re filling an order that exists on their off-chain orderbook which is then submitted to the Ethereum network to be mined into the blockchain. Sometimes the order you are trying to fill expires or is filled by another trader (or frontrunner) before your transaction is mined. This causes your transaction to revert. Lowering the gas price of your trade can increase the odds of this occurring.
